There seems to have been a typo in the latest update, in the registry writing routine, causing Mailto not work (eg. if you click on mailto link on any webpage, Pocomail/Barca will not open new message editor).
Thank you Bruce for discovering the cause!

Running the executable inside the archive, will change the wrong registry key location (if present) to the correct one.

Step by step instructions:
- download the file relevant to your software
- double click on the downloaded zip archive to open it
- double click on the executable file (pocomrf.exe or barcamrf.exe or barcapromrf.exe) to run it
That's it. There will be no messages, executable runs for a second or so.

If asked by your security program (antivirus, ...), allow a (one-time if choice is available) registry access and writing for this executable.

I should have also noted that if someone is afraid of running the fix, it's possible to get same effect by manually editing your Windows registry...just say so if you prefer that and I'll add the details.

It still doesn't work for me. I've run the exe as administrator but it doesn't make PM the default. If I click on Make Default in PM it seems to work but when I go to Default programs Vista say Unknown program and nothing opens. I've also tried without clicking anything in PM.

The patch program did not work for me either. In another thread (referred to above), someone pointed out to root of the problem which is in the registry. I simply went to the registry here:

HKEY_CLASSES_ROOT\mailto\shell\open\command

and made this the value for that registry key:

"C:\Program Files\PocoMail\Poco.exe" /m "%1"

(the quotes are necessary).

I presume this registry change is the sort of thing that the patch does. I'm going to guess that in my case the patch didn't work because of some assumption the patch makes about what the mucked up key is supposed to look like. In my case that mucked up key used a DOS name for the directories -- perhaps the patch didn't expect that form (or at least not the exact one that was in my registry).

I also manually changed the registry as Sandy shows but a mailto still opens Thunderbird. I've tried change in the Default Programs but the mailto option, after selecting PM to be the default shows it's an "unknown program".

"Pocomail" (4. is still the best mailer I ever used. And I often come to the forum for a whiff of nice air of passionate users!
I had not noticed the "Mailto problem", but trying to use "Mailto" with "Time and Chaos", and "Digital Phonebook", I noticed it did not work. After checking PM was registered in IE > Tools as "default", I ran the file given by Tomas. At first, it did not work. Then I tried to go back to "Pocomail" Options, to re-register it as "Default", and it worked! Thanks Tomas and Luxor and all the "users -who-help"!
I will continue to introduce PM to my friends, but as it is in English only, it slows up their wishes to try it!
Have a nice ad glorious Summer!
All the best from Brittany!

I'd be interested in this fix as well. I tried all of the above without success. I'm unable to click on a link on a webpage to send something via Barca, or to use other programs with a 'send to email' function. It isn't critical, but it can be pretty inconvenient.

Windows 7 64-bit (and presumably Vista 64-bit) places 32-bit programs like Barca and Pocomail into the Program Files (386) directory (only 64-bit programs are placed into the Program Files directory).

To get Barca to be default, I had to start it with Administrator privileges, but that didn't fix the problem altogether because clicking on a mailto: link simply opened Barca but didn't create a new message window.

I tried setting Barca so it opened with Administrator privileges all the time, but that simply meant that I had to deal with the confirmation dialogue every time Barca ran and it didn't fix the issue.

I tried the script for Barca, but assume that it didn't know how to deal with 64-bit windows.

However, I modified Sandy's registry edit to make it work for 64-bit Windows 7:

HKEY_CLASSES_ROOT\mailto\shell\open\command

and made this the value for that registry key:

"C:\Program Files (x86)\Barca2\Barca.exe" /m "%1"

(as Sandy said, the quotes are necessary). Presumably, Pocomail will work with the following value:

"C:\Program Files (x86)\PocoMail\Poco.exe" /m "%1"

I don't have a Vista system to test this solution, but hopefully it will help those having problems with Vista as well as Windows 7 users.

No matter what I tried, in Windows 7 Pocomail always opens an email link with the email address shown as a mailto: attachment.

As others have mentioned, the New mail window does open normally, but you are started out on the Attachments tab with mailto:email@address.com and a white box with red circle through it.

This may be simple but until a permanent solution is found I discovered that if you double-click on the mailto: address that is shown under the Attachments tab, an additional New mail window will open and the address will be correctly formatted in the To: field.

I realize it's an extra step and an extra window to close, but at least it works.

Everything else I've tried to do under Windows 7 with Pocomail has worked so far.

Thanks for the tip. I hadn't realized that clicking the link would open a new window that worked.

I never saw the link in the attachment until I set up PocoMail 4 for a client in a new 64-bit Windows 7 computer. I wonder why it is intermittent. If we could figure out the trigger (i.e. duplicated the issue on any Windows 7 machine) Poco could likely fix it.

I run Barca 2 rather than PocoMail 4, so I wonder if that has anything to do with it.
